What is the difference between a first-time mistake and repeating a known bad action?

A developer can make a mistake one time. A developer must not repeat a known mistake. Repeating a known mistake shows negligence.

The rule

A developer can make a mistake one time.

A developer must not repeat a known mistake. Repeating a known mistake shows negligence.

Making a mistake for the first time is part of learning. This is acceptable. Repeating a mistake that is already known to be bad is not acceptable. This shows a lack of care or attention. A developer must check past information before acting. This helps to avoid repeating errors. The goal is to learn from mistakes, not to make them again.

A developer writes code that causes an error. The error is new. The developer learns from this error and fixes the code. This is acceptable. Later, the developer writes new code. The new code uses the same bad pattern that caused the first error. The developer knew this pattern was bad. This is not acceptable. The developer repeated a known mistake.

Questions people ask

More from the same record, pulled by shared topic — not written new for this page.

What should a developer do before writing any code that uses an external API?

Before writing any external API code, a developer must read specific policy files. These files include rules for starting a session, handling retries, and using the central API coordinator.

How can a developer recover after a coding failure?

When a developer's code fails, the developer must stop typing. The developer should take a short break, perhaps 30 seconds.

When should a developer use the Batch API, and what are the risks?

The Batch API is best for tasks with more than 50,000 calls. The cost savings must be worth a 24 to 48-hour wait time.

How should a developer handle errors when calling an external API?

When a developer's code calls an external API, it should try only one time. The developer must not use loops to retry the call.

What to remember

A developer can make a mistake one time. A developer must not repeat a known mistake. Repeating a known mistake shows negligence.
